Chute construction



Patented Jan. 13, 1931 UNITED STATES PA T OFFICE" KENNETH F. TRIGGS, OF HUNTINGTON, INDIANA, ASSIGNOR TO THE MAJESTICOOM- PANY, OF HUNTINGTON, INDIANA, A CORPORATION GHUTE CONSTRUCTION V Application filed May 31,

This invention relates to a coal chute construction and one wherein certain simplifiications have been obtained.

The chief object of the invention is to i simplify the construction of a coal chute device, whereby the same may readily be applied to structures that have been built and in which an opening has been made for the mounting of the chute therein.

One feature of the invention consists in the adjustable peripherally enveloping clamping arrangement provided and the self cleaning or non-interfering character thereof.

The full nature of the invention will be fully understood from the accompanying drawings and the following description and claims.

In the drawings Fig. 1 is a perspective view of a coal chute construction with the closure opened.

Fig. 2 is a transverse sectional view taken on line 22 of Fig. 1 and in the direction of the arrows.

In the drawings indicates a tubular construction, preferably rectangular in form and of a length that is sufficient to accommodate substantially all thicknesses of walls or foundations. Secured to the forward edge of said tubular member is a face plate 11 having an opening 12therein. The face plate includes the cars 13 upon which is pivotally supported a closure 14, which preferably has a latch construction indicated generally at 16 on its inner face. The chute may, if desired, be provided with an inclined extension 17 havin the stops 18 and the linkage support 19 therefor. The tubular member upon two opposite sides includes a plurality of substantially semi-circular openings 20, the same being punched therefrom, and the surplus metal being turned back as at 21 to form a double reinforced and curved edge 22.

Telescopically mounted upon the opposite or inner end of the tubular member is a clamping member, herein shown in the form of a welded angle iron having the base portion 23 and the outwardly projecting flange portions 24. Flange 2a is apertured as at 25 in substantially horizontal alignment with 1930. Serial No, 458,396.

the opening 20. A hook-bolt 26 havin githe that the strain is taken by a reinforced-por- 1 tion and that the anchoring means are self clearing, in that the chute exposed portions of the'hook-bolts are directed rearwardly. The'face plate 11 and the peripherally enveloping telescopic clamping'member 24, clampingly and rigidly mount the entire chute construction in the opening 31 of the wall or foundation. The telescopic member may be reversely positioned, that iswith the base portion 23 oppositely directed, or a different form of clamping memberinay'be substituted. I

The invention claimed is 1. A coal chute construction including an exterior exposed wall engaging openingdefining frame having an opening therein, a closure for said opening, a tubular construction extending rearwardly from the frame and positioned in the wall opening, a wall clamping member peripherally enveloping and slidably mounted on the tubular con-- struction and bearing upon the wall adjacent the opening therein, said tubular portion construction including a perforation in a plurality of sides, and a hook-bolt for each perforation and having the, hook portion seatable therein and the other end adjustably associated with the'wall clamping member.

2. A coal chute construction including an exterior exposed wall engaging opening defining frame having an opening therein, a

closure for said opening, a tubular construction extending rearwardly from the frame and positioned in the wall opening, a wall clamping member peripherally enveloping and slidably mounted on the tubular construction and bearing upon the Wall adjacent the opening therein, said tubular portion construction including a perforation in a 5 plurality of sides, and a hook-bolt for each perforation and. having the hook portion seatable' therein and the other-end adjustably associated with the wall clamping member, the main portion of the hook-bolt being posi- 10 ti'o'ned without the tubular construction and the hook portion thereof being positioned within the tubular construction andrear- Wardly directed providing a minimum of interference in the chute.

3. A coal chute construction including an exterior exposed-Wall engaging opening defining frame having an opening therein, a closure for said opening, a tubular construction extending'rearwardly from the frame and positioned in the Wall opening, a Wall clamping member peripherally enveloping and slidably' mounted on the tubular construction and bearing upon the Wall adjacent the opening therein, said tubular portion construction including a perforation in a plurality of sides, and a hook-bolt for each perforation and having the hook portion seata-ble therein and the other end adjustably associated with the Wall clamping member,

the main portion of the hook-bolt being posiioned Without the tubular. construction and the hook portion thereof being positioned within the tubular construction and rearwa-rclly directed providing a minimum of interference in the chute, the perforations in said tubular construction being formed by piercing the same and turning rearvvardly the pierced portion of the metal for forming a reinforced bearing for the curved portion of the hook-bolt.

In witness whereof, I have hereunto afiixed my signature.
